Key Differentiators
- Extended temperature range (-55°C to 125°C) (vs LTM4700IY#PBF)
- Military-grade reliability (vs LTM4700EY#PBF)
- Same electrical performance (vs LTM4700IY#PBF)
Design Notes
The LTM4700MPY#PBF can dissipate significant power at full load. For example, at 100A output and 1.8V, power dissipation is approximately 18W (assuming 90% efficiency). Ensure adequate airflow and consider a heatsink or thermal pad. The BGA package has an exposed thermal pad that must be soldered to a large copper area for heat spreading. Follow the layout guidelines in the datasheet for optimal thermal performance.
Place input and output capacitors close to the module pins to minimize parasitic inductance. Use multiple vias to connect the thermal pad to the ground plane. For high-current paths, use wide traces or copper pours to reduce resistance and heat. The PMBus lines (SDA, SCL) should be routed with proper pull-up resistors and kept away from noisy switching nodes.
Do not exceed the absolute maximum input voltage of 16V. Ensure the PMBus address is correctly set to avoid conflicts on the I2C bus. The output voltage is set via PMBus or external resistors; verify the configuration before power-up. Also, consider the input current rating and use appropriate input bulk capacitance to handle transient loads.
